When a person inadvertently ingests a poisonous substance, we are taught to act quickly. The poison must be removed before damage is done. Accordingly, responses to our inquiries concerning unconventional business practices demand immediate attention.
I have contacted [COMPANY] on several occasions regarding [ITEM1]. As a professional, I know this is not an insurmountable dilemma once the proper resources are dedicated. The key is making our concern a [COMPANY] priority by giving it attention.
[COMPANY NAME]'s stance has not changed. We still insist that [ITEM2] be [ITEM3] as soon as possible. Let's not waste any more valuable time; your unprofessionalism is destroying any possibility of future business with [COMPANY NAME]. I hope to hear from [COMPANY] within the next week with confirmation that the issue has been resolved to our mutual satisfaction. You know what it feels like when you're ignored.
Sincerely yours,
